The old Scottish-Dalriadan name MacLochlainn is derived from the personal name Lachlann. The Gaelic form of the name is Mac Lachlainn, denoting the son of Lachlann. Although most feel Lachlan Mor, a great Chief who lived by Loch Fyne in the thirteenth century, is the Clan founder, the legend of descent from the ancient Gaelic King, Niall of the Nine Hostages, who reigned in 400 AD, offers some clues as to the clan's early origins.

Lochlann, in old Gaelic means literally, 'Norway,' and was the favorite Christian name of the royal house of O'Neill in Northern Ireland, a house descended from Niall of the Nine hostages, and said to be the family with the oldest history in Europe. A branch of the O'Neill's took the surname MacLochlain and soon became rival Kings to the O'Neills.

King Brian O'Neill slew the last King Domnall MacLochlainn. His son Anrothan, who was ancestor of the MacLachlans in Scotland, married the daughter of the King of Scots, thereby gaining the inheritance of Cowall and Knapdale in Scotland. Anrothan MacLachlan was progenitor of the MacLachlans of Strathlachlan, the Lamonts, the Lyons, the MacSorleys, the MacEwans, and the MacMillans. It was in the mid-twelfth century that each of these branches separated into distinct entities.

Early Origins of the MacLochlainn family

The surname MacLochlainn was first found in Argyllshire (Gaelic erra Ghaidheal), the region of western Scotland corresponding roughly with the ancient Kingdom of Dál Riata, in the Strathclyde region of Scotland, now part of the Council Area of Argyll and Bute, where this Clan first settled in Scotland in 1100 when Lachlan was heir of Fergus, Lord of Galloway. In 1238, a charter recorded Lachlan Mor's father increasing the endowment to Paisley Abbey.

When, in 1292, King John Baliol erected Argyll into a sheriffdom, Gillescop MacLachlan was one of the twelve principal barons whose land it encompassed. In 1296, Ewen MacLachlan was forced to swear loyalty to the English King Edward I, but this loyalty was formally changed back to Scotland in 1305, when Gillescop MacLachlan, like his neighbors the Campbells, swore allegiance to Robert the Bruce. Gillescop was a member of the Barons of Bruce's first parliament at St. Andrews, in 1308. 1

King John of England (reigned: 1199-1216) was also known as John Lackland from the Norman French, "Johan sanz Terre" or "John without land."

Migration of the MacLochlainn family

These settlers arrived in North America at a time when the east was burgeoning with prosperous colonies and the expanses of the west were just being opened up. The American War of Independence was also imminent. Some Scots stayed to fight for a new country, while others who remained loyal went north as United Empire Loyalists. The ancestors of all of them went on to rediscover their heritage in the 20th century through highland games and other patriotic Scottish events. The MacLochlainn were among these contributors, for they have been located in early North American records: William Lachlan, who arrived in Pennsylvania in 1847; Thomas Laughlin settled in Virginia in 1654; Adam Laughlin settled in New England in 1805; John Laughlin settled in Pennsylvania in 1823.

The MacLochlainn Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Fortis et fidus
Motto Translation: Brave and trusty.
